Answer:
Answer is A.. ( i.e. 3x + 7 )
Answer:
Step-by-step explanation:
I will assume that you meant: (-3/7)(y-28) - (1/21)y
Using the distributive property of multiplication, we get:
(-3/7)y + (3/7)(28) - (1/21)y
Let's first reudce the middle term. We get: 12
Then we have:
(-3/7)y + 12 - (1/21)y
Here there are two different denominators. We must combine the y terms. The LCD here is 21. Multiplying (-3/7)y by 21/21, we get the equivalent:
-9y
------ + 12 - (1/21)y
21
or:
-9y 21
------ + 12----- - (1/21)y
21 21
Combining the y terms, we get (-10/21)y:
-10y 252
------- + -------- = (1/21)(-10y + 252)
21 21
Does this answer your question
Answer:
x = -2/ 3
Step-by-step explanation:
in order to cancel out the logs they should have common bases

we can write 25 as 5²

we know that the reciprocal of the exponents of the bases are multiplied to the log

and now since the logs have common bases

we're left with


<u>x = -2/ 3</u>
